The Multiquip 0642008900 Fuel Cock is a genuine OEM component designed for GA-2.3R2, GA-3.6RZ2, and GA-3.6RZ3 portable generators. As a direct factory replacement, this part restores proper fuel flow control to your generator, ensuring the engine receives the correct supply of fuel when the machine is in operation. Sourced directly from Multiquip, part 0642008900 is built to the same specification as the original, so you can install with confidence and get your equipment back to work quickly.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to Multiquip's original design tolerances, this fuel cock delivers the same shut-off response and flow rate as the part it replaces — critical for consistent engine fueling.
- Drop-In Replacement — Matches the original mounting configuration and fuel line connections on compatible generator models, allowing straightforward installation without modification.
- Confirmed Fitment for Key Generator Models — Verified compatible with GA-2.3R2, GA-3.6RZ2, and GA-3.6RZ3 portable generators, so you can order knowing this is the correct part for your machine.
- Restores Reliable Fuel Shutoff Control — A worn or leaking fuel cock can cause uncontrolled fuel flow, hard starting, or engine flooding; replacing it with 0642008900 returns full control of your generator's fuel supply.
- Fuel System Safety — A properly functioning fuel cock is essential for safe refueling, storage, and transport of portable generator equipment, preventing unintended fuel release.
The fuel cock is a manual valve that controls the flow of fuel from the tank to the engine's carburetor. When opened, it allows fuel to travel through the fuel line to support engine starting and operation; when closed, it cuts off that supply for safe shutdown, refueling, or storage. Over time, the valve seat and internal seals can wear or crack, leading to fuel leaks, improper shutoff, or restricted flow — any of which can affect starting performance or create a safety hazard. Replacing a faulty fuel cock with a genuine Multiquip part restores full control over the fuel circuit.
